LAND-MARKER FOR CORN-PLANTERS.

To all whom it may concern:

Be it known that I, IVAN L. CATLIN, a citizen of the United States, residing at Herrin, in the county of Williamson and State of Illinois, have invented certain new and useful Improvements in Land-Markers for Corn-Planters, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to land markers for corn planters.

The object of the invention is to provide an apparatus of this character which shall be exceedingly simple of construction, efficient and durable in use, positive in operation, and the parts of which shall be so constructed and arranged that while obtaining the maximumresults in operation, danger of derangement and breakage in use will be reduced to the minimum.

A further object is to provide a land marker in which, by a novel arrangement of mechanism, the marker arm shall be absolutely under the control of the operator,-

whereby at the approach of the end of the row the arm may first be raised and then again lowered into operative position.

With the above and other objects in view, as will appear as the nature of the invention is better understood, the same consists in the novel construction and arrangement of parts of a land marker for corn planters as will be hereinafter fully described and claimed.

In the accompanying drawings forming a part of this specification, and in which like characters of reference designate corresponding parts: Figure 1 is a top plan view of a land marker constructed in accordance with the present invention; Fig. 2 is a longitudinal sectional view taken on the line 22, Fig. 1; Fig. 3 is a transverse sectional view taken on the line 33, Fig. 1; and Fig. 4 is a similar view taken on the line 44, Fig. 2.

Referring to the drawing, 1 designates the frame of the machine, which is of open rectangular form and has secured to its two side members at the front, two connected bars 2 and 3, to which is attached a tongue 4 of the usual or any preferred construction.

Extending through the side bars of the frame and journaled therein is an axle 5 carrying ordinary ground wheels 6. This Specification of Letters Patent.

Application filed June 17, 1914. Serial No. 845,694.

axle has mounted upon it, in proper spaced relation, a pair of miter gears 7 and 8, each of which is provided with a hub 9, and each hub isprovided with a pair of alined slots 10 through which projects a pin 11 rigid with the axle. The gears are held normallyspacecl apart by a coiled spring 12, the ends of which bear against the opposed faces of the gears, the outward movement of the latter upon the shaft being checked by the pins 11. Also mounted upon the axle 5, exteriorly of the two hubs 9, are two collars 13, each of which carries two oppositely alined pins 14, and these pins are engaged by the arms of a yoke 15, each of these yokes being constructed from two pieces of metal, the upper one 16 of which is L- shaped and constitutes a shifting lever for the collar with which it connects, and the other arm 17 of which is bent around the collar 13, the terminals of the arms being slotted to receive the pin. The two arms forming the yoke are pivoted at 17 to a bracket 18 that is rigidly secured to a bar 19 extending transversely of the frame 1, and having its ends 20 bent at right angles to its length and rigidly secured to the side members of the frame. To the front end of the shifting lever 16 is connected one end of alink 21, the other end of which is connected with an eye 22 carried by a foot lever 23 hinged to the bar 19.

Journaled in the bar -19 and the rearbar 24:-

of the frame 1 is a shaft 25 the inner end of which carries a miter gear 26 that is normallyout of mesh with the gears 7 and 8,

the outer end of the shaft being projected beyond the frame member 24' and having connected with it an L-shaped socket 27 that is designed to receive one end of a marker arm 28, the other end of which carries the marker 29 which may be of the usual or any preferred construction. The shaft 25, at a point adjacent to the inner side of the frame member 24 carries an eccentric'30, the periphery of which is provided with three notches 31, 32 and 33, the

eccentric being rigid with the shaft 25 so as to turn therewith. The notches are adapted.

to be engaged by a rigid dog 84: carried by a lever 35 that is fulcrumed upon a bracket 36 carried by the frame member 24, the bracket having secured to it a leaf spring 37 which bears against the under side of the lever and tends to hold the dog in engagement with the periphery of the cam. The inner end of the lever 35 is connected by links 38 with the two foot levers 23, so that upon either of the levers being depressed, the lever will be moved in a direction to throw the dog out of engagement with either one of the notches in the eccentric with which it is engaged.

In order to guide the marker arm for arcuate movement through one-half of a circle, more or less, the marker has connected with it one end of a rod 39, the other end of which carries a ring 40 and is designed to traverse an arched rod 41 carried by the bar 2.

In the operation of the apparatus, assuming that the machine is about to start a new row, under which condition the marker arm will occupy a substantially vertical position, the operator presses on one or the other of the foot levers 23, thereby releasing the dog 34 from engagement with the cam, and this movement also, through one or the other of the levers 16, will impart an inward motion to the collar 13, and thereby bring either of the miter gears '7 and 8, according to which of the foot levers is pressed, into engagement with the miter gear 26, causing the same to rotate and turn the marker arm toward the ground. Just before it reaches the ground, the operator removes his foot, whereupon the spring 12 will perform its function, and throw the miter gears 7 and 8 out of engagement with the gear 26. As the dog 34, at this point in the operation, is upon the smooth surface of the cam 30, there will be nothing to prevent the marker arm from dropping by gravity and bringing the marker into engagement with the ground. As soon as the end of the row has been reached, and the machine is to be turned, the operator will press upon one of the foot levers, thereby bringing one or the other of the gears 7 and 8 into engagement with the gear 26, whereupon the shaft will be rotated until the dog 34 enters in any one of the series of notches 31, 32 and 33, and the operator now lifts his foot to unmesh the gear 26. As soon as the turn has been made, the same foot lever is again pressed, whereupon the marker arm isagain caused to drop to bring the marker into engagement with the ground.

, It will be seen from the foregoing description that although the improvements herein ,described are simple in character, they will be thoroughly efficient for the purposes designed, and will coaet in the production of a practical and durable form of land marker for corn planters.

I claim:

1. In a land marker, the combination with a frame, an axle supported thereby and carrying ground wheels, a pair of beveled gears loosely mounted for longitudinal movement on the axle but held from rotary movement thereon, a spring for holding the gears normally spaced apart, a collar coacting with each of the gears, treadle mechanism connected to the collars for shifting either of the gears on the shaft inwardly, a longitudinal shaft carried by the frame, a beveled gear on the latter shaft normally out of mesh with the first named gears, a rotary marker arm connected with the longitudinal shaft, a notched eccentric carried by the latter shaft, a lever supported by the frame and arranged to engage the eccentric, and connections between the lever and the treadle mechanism whereby when the latter mechanism is actuated, one or the other of the beveled gears on the axle Will be brought into mesh with the gear on the longitudinal shaft, and thus cause the marker arm to be moved to a position to be engaged by the dog on the lever, thus to hold the arm out of engagement with the ground.

2. In a land marker, the combination with a supporting frame, an axle supported 1 thereby and carrying ground wheels, ashaft disposed longitudinally of the frame and having its outer end provided with an L-shaped socket and its inner end with a beveled pinion, a notched eccentric carried by the shaft, a pair of pinions mounted for longitudinal sliding movement on the axle and adapted to be moved into engagement with the beveled gear on the longitudinal shaft, a spring holding the gears on the axle normally spaced apart, a lever supported by the frame and having one end provided with a dog arranged to engage with the notches in the eccentric, collars mounted upon the axle adjacent to the gears, L-shaped levers pivoted to the frame and connected with the collars, treadle mechanisms, connections between the L-shaped levers and the treadles and between the treadles and the lever, a marker arm carried by the socket, an arch rod carried by the frame, and a rod connected at one end with the marker arm and having its other end slidably connected with the arch rod.

In testimony whereof I hereunto afiix my signature in the presence of two witnesses.
